The Vienna Genesis: the Oldest, Well-Preserved Illustrated Biblical Codex

Considered the oldest, well-preserved, illustrated biblical codex, the Vienna Genesis  is an illuminated manuscript, probably produced in Syria.  It is preserved in Vienna at the Österreichische Nationalbibliothek (cod. theol. gr. 31).

"The text is a fragment of the Book of Genesis in the Greek Septuagint translation. The text is frequently abbreviated. There are twenty-four surviving folios each with a miniatures at the bottom of both sides. It is thought that there were originally about ninety-six folios and 192 illustrations. It is written in uncials with silver ink on calfskin parchment dyed a rich purple. This shade of purple dye was also used to dye imperial cloth.

"The illustrations are done in a naturalistic style common to Roman painting of the period. The manuscript's illustrations are, in format, transitional between those found in scrolls and later images found in codices. Each illustration is painted at the bottom of a single page. However, within a single illustration, two or more episodes from a story may be included, so that the same person may be represented multiple times within a single illustration. There are both framed and unframed illustrations. The illustrations contain incidents and people not mentioned in the text of Genesis. These incidents are thought to have been derived from popular elaborations of the story or from a Jewish paraphrase of the text" (Wikipedia article on the Vienna Genesis).
